METAL CAN.

SPEG'LILLCA'IION forming part of Letters Patent No. 703,445, dated July 1, 1902.

` Application filed October 12,1901. Serial No. 78,400. (No model.)

.To all wil/m, it may concern:

Be it known that I, FRANCIS RIMcCoLL, a

citizen of the United States, residing at Chi` cago, county of Cook, State of Illinois, havein.- vented a certain new andusefulIm'provement in Metal Cans; and I declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which it pertains to make and use the Io same, reference being had tothe accompanying drawings, which form a part of this speciiication.

My invention relates in general to metallic cans, and more particularly to thattype of I5 cans in which the cover is soldered to the body portion and is removed therefrom by means of a key.

In cans of the class referred to it is desirable that a somewhat-extended engaging sur- 2o face should be provided between the can and its cover in order that sufficient solder may be interposed to securely fasten the cover on the can and at the same time avoid either so extending the body portion beneath the coverV as to interfere with the removalof the contents of the can or so extending the cover over the body portion as to impede its ready detachment therefrom.

The object of my invention is to provide a 3o metallic can of the class described in which the cover and body portions overlap suiiciently to afford the requisite surface for the solder Without either unduly restricting the top opening of the can or preventing theeasy removal of the cover by the use of a key.

My invention consists, essentially, in a metal can the body portion of which is provided With an integral,inwardly-extending shoulder and a Aflange depending therefrom, 4o while the cover is provided with a raised outwardlyprojecting flahge and a depending shoulder adapted to closely engagewithzthe shoulder and flange, respectively, von the body portion, thereby affording sufficient overlapping surfaces to receive the amount of solder necessary to secure the cover to the body portion of the can. My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in WhichA ,l

Figure l'is a perspective view of the can and its cover beforebeing soldered together; Figf, a vertical section through the can, showing the cover secured thereto; and Fig. 3, a detail View showing the engagement be tween the body portion of the vcan and the cover. Y

Same reference characters are used to indicate the same parts in the several figures of the-drawings.

Reference-letter A indicates the body portion of the can, which maybe of any desired dimensions and shape, it being for convenience shown of a size commonly used for canning sardines. The body portion A may consist of a strip of metal the endsof which are united, as at a, in any suitable manner-as, for instance, by solder. One peripheraledge of the Vloody portion A is provided with an inwardly-extending integral shoulder a', preferably horizontally disposed, from the inner edge of which a iiange a2 depends in substantially a vertical direction.

vThe cover B is provided with a raised horizontalange b,' preferably of a width substantially equal to the Width of the shoulder a' of the body portion of the can. Between `the flange b' and the depressed portion b of the cover B is formed a shoulder b2, which is preferably substantially vertical and of Va depth` approximately corresponding to the depth of thedepending flange a2 of the body portion of the can.

The bottom C of the can may be of any preferred shape and may be secured to `the body portion A in any desiredV manner.' In the drawings, particularly Fig. 2, the bottom C is illustrated as provided with a vertical peripheral flange C', which is received within the distended lower edge A of the .body portion of the can, the bottom Cengaging the shoulder formed between the distended edge A and the rest of the body portion of the can. The bottom C may be secured within the distended edge A' of the can in any suitable manner. I

The cover B is provided with any preferred means to be engaged by a can-key to permit the removal of the cover from the can. In Fig. l the cover is shown as provided with an integral extension B', located at one of the corners of the cover.

The manner in which the parts of my invention are assembled will be readily linderstood from the foregoing description and is as follows: The cover is placed upon the body portion A of the can, so that the peripheral raised portion b' will lie above the inwardly-extending shoulder a/ of the can, the relative dimensions of the cover B and body portion A being such that the shoulder b2 closely engages the flange a2, depending from the edge of the shoulder a'. Prior to fitting the cover upon the body portion of the can solder c' is interposed between the shoulder ct and flange d2 of the body portion and the flange b' and shoulder b2 of the cover, respectively, thereby securely fastening the cover to the body portion of the can. When it is desired to remove the cover, a key of any suitable form is engaged with the projection B and the cover thereby torn away from the body portion of the can by detaching the same along the line of the interposed solder.

From the foregoing description it is evident that I have produced a metallic can the body portion and cover of which overlap a sufficient distance to aiford an extended surface for the intel-position of the solder and without either unduly restrict-ing the opening at the top of the can or extending the cover over the body portion, so as to interfere with the ready opening of the can by the use of a key in the wellknown manner.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

l. In a metal can, the combination with a body portion having an inwardly-extending integral shoulder and a downwardly-projecting flange, of a covervhaving a raised peripheral flange and ashoulder formed between the raised flange and the cover whereby extended engaging surfaces between the body portion and the cover are provided, said cover engaged to said downwardly-extending ange by s01- der, substantially as described.

2. In a metal can, the combination with a body portion having an inwardly-extending horizontal integral shoulder and a down wardly-projecting vertical flange, of a cover having a raised horizontal peripheral flange corresponding substantially in width to the shoulder on the body portion and a vertical depending shoulder corresponding substantially in depth to the flange on the body por tion, whereby extended engaging surfaces be tween the body portion and cover are provided, said cover engaged to said downwardly projecting vertical flange by solder, substantially as described.

3. In a metal can, the combination with a body portion having an inwardly-extending integral shoulder and a downwardly-projecting flange, of a cover having a raised peripheral flange and a shoulder formed between the raised flange and the cover whereby extended engaging surfaces between the body portion and the cover are provided, solder interposed between both of said extended engaging surfaces and thereby securely fastening the cover to thc body portion of the can, and means projecting from the cover adapted to be engaged by a key, substantially as described.

In testimony whereof I sign this specificad tion in the presence of two witnesses.
